| 摘 要： | 将最小二乘配置方法的高斯型经验协方差函数模型应用于区域跨断层形变曲线的异常辅助识别。通过川滇地区跨断层形变对芦山7.0级、康定6.3级、鲁甸6.5级等地震的前兆异常判定曲线，说明最小二乘配置内插拟合可以进行区域跨断层水准形变曲线的趋势模拟和辅助查找区间异常特征，对于跨断层形变曲线异常识别有一定意义。

| Abstract: | The Gauss-function model, based on least square collocation, is used in anomaly assisted identification of regional cross-fault deformation characteristic curves. The precursory anomaly judgment examples of regional deformation of cross-fault in Lushan Ms7.0, Kangding Ms6.3, Ludian Ms6.5 and other earthquakes, show that least square collocation can be fitted in regional cross-fault deformation and helps in identifying anomaly characteristics. The method has certain significance for the deformation of cross-fault identification． |
